[PATCH v9 0/7] ARM: berlin: add AHCI support

[Antoine Ténart]

This series adds the support for Berlin SoC AHCI controller. The
controller allows to use the SATA host interface and, for example, the
eSATA port on the BG2Q.

The series adds a PHY driver to control the two SATA ports available,
and adds a generic compatible to use the existing ahci_platform driver.

Also enable the eSATA interface on the BG2Q DMP.

Changes since v8:
	- stopped reset the controller from the PHY driver
	- removed fixed array sizes
	- got rid of the custom to_berlin_sata_phy_priv() macro
	- added dependency to HAS_IOMEM

Changes since v7:
        - got back to the each PHY as a sub-node representation
        - renamed the power bit in the PHY driver

Changes since v6:
        - added the 'clocks' property and support in the PHY driver
        - updated the PHY compatible

Changes since v5:
        - rebased on top of v3.16-rc1
        - added the 'clocks' property in the sata node

Changes since v4:
        - updated PHY driver as tristate
        - handled the case were no SATA port is enabled
        - updated the compatible to a generic one
        - cosmetic fixups

Changes since v3:
        - moved all PHY operations to the PHY driver
        - removed PHY sub-nodes
        - removed the custom Berlin AHCI driver and switched to
          ahci_platform
        - added multiple PHYs support to the libahci_platform

Changes since v2:
        - modeled each PHY as a sub-node
        - cosmetic fixups

Changes since v1:
        - added a PHY driver, allowing to enable each port
          individually and removed the 'force-port-map' property
        - made the drivers a bit less magic :)
        - wrote a function to select and configure registers in the
          AHCI driver
        - removed BG2 / BG2CD nodes
